Lorax,
We need Co2 as part of our system as others have pointed out.
Humans would die on a diet of pure oxygen.
Our food cycle depends on Co2. We live in a carbon based world.
Carbon dioxide levels have moved up and down through natural causes forever and will continue to do so regardless of what we do.
To demonize CO2 is just nonsense. Its a political ploy to attempt to get the masses on side. The masses however have not bought that story.
